Description
FA7700V/FA7701V are the PWM type DC to DC converter control ICs with 1ch output that can directly drive power MOSFETs. These CMOS devices have high breakdown voltage and achieve low power consumption. They offer many functions equivalent to our conventional version bipolar ICs – FA76XX series- with the added merits of output ON/OFF control function, direct driving Nch/Pch MOSFETs, low power consumption, higher frequency operation, and fewer external discrete components.
Specifications and features
- Wide range of supply voltage: VCC=2.5 to 20V
- FA7700V—for boost, flyback converter (Maximum output duty cycle is 80%)
- FA7701V—for buck converter (Maximum output duty cycle is 100%)
- Output stage consist of CMOS push-pull circuit, achieves a high-speed switching of external MOSFETs
- High accuracy reference voltage (Error amplifier): 0.88V±2%
- Soft start function
- Adjustable built-in timer latch for short-circuit protection
- Output ON/OFF control function
- Less external discrete components needed (2 components less than conventional version of the equivalent products)
- Low power consumption
- Stand-by current: 40μA(typ.)
- Operating current: 1.2mA(typ.) (including error amplifier output current and oscillator current)
- High frequency operation: 50kHz to 1MHz
- Package: TSSOP-8 (thin and small)
Application Scenarios
The FA7701V-A2TE model is widely used in various applications including boost, flyback, and buck converter circuits. It is suitable for driving power MOSFETs and provides high-speed switching capabilities. The low power consumption and adjustable built-in timer latch make it suitable for applications requiring short-circuit protection. The compact TSSOP-8 package allows for space-saving designs.
